As shown in fig. 1, an embodiment of the present invention provides a method for remotely controlling a server cabinet to access and leave a power grid, where the method adopts the following principles:
first, the executive programs that are on-grid and off-grid need to be packaged as Dropin and Dropout, respectively.
The execution logic of Dropin is: firstly, collecting the opening and closing states of the circuit breaker and the isolating switch, sending a closing signal to an isolating controller when no error exists, continuously and circularly inquiring the information of the transmission ports of the isolating switch and the main control computer, and finishing circular inquiry when the information that the circuit breaker is closed exists in the transmission ports; and sending a closing signal to the circuit breaker controller, continuously and circularly inquiring information of the transmission ports of the circuit breaker and the main control computer, and finishing circular inquiry when the port has the closing information of the circuit breaker.
The execution logic of Dropout is: the method comprises the steps that the opening and closing states of a circuit breaker and a disconnecting switch are collected firstly, when no error exists, a disconnection signal is sent to a circuit breaker controller, then port information is transmitted between the circuit breaker and a main control computer in a circulating mode, and when the port has the disconnection information of the circuit breaker, the circulating query is finished; and sending a disconnection signal to the isolating controller, continuously and circularly inquiring the isolating switch and the master controller to transmit port information, and finishing circular inquiry when the isolating switch is disconnected at the port.
And then, according to the actual requirement of power grid access or leaving, running a corresponding execution program on the main control computer, and controlling the corresponding server cabinet through the CAN bus to complete the whole implementation process of the execution program.
It should be noted that during the execution of the steps of the method, if any wrong feedback information is received, an alarm signal is sent out.
In an actual application scenario, a certain number of pre-or post-operations need to be added to the power grid access or departure operation to meet the needs of the site, which is described in detail by taking the cabinet a as an example, and a specific implementation flow is shown in fig. 2.
When cabinet a needs to leave the grid: the main control computer firstly accesses the cabinet RMC to inquire the working condition of each server in the cabinet, and if the main control computer is working, the main control computer firstly sends a starting signal to the standby cabinet B to take over the work of the cabinet A; if there is no working or standby cabinet, or the standby cabinet B has taken over the work of the cabinet a, the main control computer sends a disconnection signal to the circuit breaker controller of the cabinet a, and then the circuit breaker controller disconnects the circuit breaker of the cabinet a from the power grid. And at the moment, the main control computer performs cycle detection until a circuit breaker controller of the cabinet A has a feedback signal that the circuit breaker is disconnected. The main control computer sends a disconnection signal to the isolating controller of the cabinet A, and at the moment, the main control computer performs cycle detection until the isolating controller of the cabinet A has a feedback signal that the isolating switch is disconnected, and the operation is completed.
When the cabinet A needs to enter the power grid: the main control computer just sends closed signal to rack A's isolating controller, later isolating controller inserts rack A's isolator into the electric wire netting, at this moment, the main control computer circulates and detects, after rack A's isolating controller has isolator closed feedback signal, the main control computer sends closed signal to rack A's circuit breaker controller again, later circuit breaker controller inserts rack A's circuit breaker into the electric wire netting, at this moment, the main control computer circulates and detects, after rack A's circuit breaker controller has circuit breaker closed feedback signal, this time operation is accomplished.
Based on the method, the technical scheme provides a set of corresponding devices in the implementation process, and the devices comprise a main control computer, a server cabinet, a breaker and a disconnecting switch. The circuit breaker and the isolating switch realize opening and closing operations by receiving instructions.
And the main control computer is used for storing and operating the executive programs accessed to the power grid and leaving the power grid, and controlling the server cabinet through the CAN bus to realize the executive operation of the executive programs.
The execution logic of the access power grid is as follows: firstly, collecting the opening and closing states of the circuit breaker and the isolating switch, sending a closing signal to an isolating controller when no error exists, continuously and circularly inquiring the information of the transmission ports of the isolating switch and the main control computer, and finishing circular inquiry when the information that the circuit breaker is closed exists in the transmission ports; and sending a closing signal to the circuit breaker controller, continuously and circularly inquiring information of the transmission ports of the circuit breaker and the main control computer, and finishing circular inquiry when the port has the closing information of the circuit breaker.
The execution logic of leaving the power grid is as follows: the method comprises the steps that the opening and closing states of a circuit breaker and a disconnecting switch are collected firstly, when no error exists, a disconnection signal is sent to a circuit breaker controller, then port information is transmitted between the circuit breaker and a main control computer in a circulating mode, and when the port has the disconnection information of the circuit breaker, the circulating query is finished; and sending a disconnection signal to the isolating controller, continuously and circularly inquiring the isolating switch and the master controller to transmit port information, and finishing circular inquiry when the isolating switch is disconnected at the port.
And the server cabinet is used for receiving the instruction of the main control computer and realizing the query and state switching of the opening and closing of the circuit breaker and the disconnecting switch.
Finally, it should be noted that: the foregoing is only a preferred embodiment of the present invention, and it will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the principle of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
